Gasoline

The chauffeur paid 54 euros for a nearly full tank of 40 liters of gasoline. If the car has an average fuel consumption of 7 liters per 100 kilometers, how many euros will it cost to travel 250 km?

Correct answer:

x =  23.63 Eur

Step-by-step explanation:

$$\begin{gathered} p=54/40=\frac{27}{20}=1.35 \\ x=250\cdot 7/100\cdot p=250\cdot 7/100\cdot 1.35=23.63\text{Eur} \end{gathered}$$
